CCNP BCMSN Notes - VLAN Trunking Protocol

VTP modes:

     Client - Rely on VLAN information advertised by a server; no local configuration possible

     Server - Have full control over VLAN creation and modification for the VTP domain

     Transparent - Does not participate in VTP but will forward advertisements

VTP advertisements:

     Summary - Sent every 300 seconds or whenever a change occurs

     Subset - Sent after a summary advertisement when a change occurs; these provide more detail to reflect the change that was made

     Advertisement Request - Issued by clients to request VLAN information

     Pruning Request - Sent from clients to servers to announce active VLANs; inactive VLANs may be pruned from the trunk

VTP configuration:

------------------------------------------------------------------------------------------------------------

     Switch(config)# vtp mode {server | client | transparent}

     Switch(config)# vtp version {1 | 2}

     Switch(config)# vtp domain <domain>

     Switch(config)# vtp password <password>

------------------------------------------------------------------------------------------------------------

VTP pruning can be enabled with vtp pruning.
